SHINGLE-SAWING MACHINE.

SPECIFCATION forming part of Letters Patent No. 325,693, datedSeptember8, 1885.

Application filed September 18, 1884.

(No model.)

T0 all 1071/0111, it may concern:

Be it known that I, WILLIS J. PERKINS, of Grand Rapids, in the county ofKent and State of Michigan, have invented certain new and usefulImprovements in Shingle-Machine Car riages; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,suoli as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in shingle-machine carriages, andmore particularly to carriages adapted to use in connection with ahand-feed shingle-machine. The operator, standing in front of a shinglemachine, pushes the carriage and shingle-bolt from him over the sawuntil the shingle is severed from the bolt, and then draws back thecarriage and remaining portion of the bolt, the shingle falling from thepoint where it was entirely severed from the bolt'into a suitable spoutor receptacle. An operator will go through this motion of advancing andret-urning the carriage from twenty-iive thousand to iifty thousandtimes per day, the number varying according to his skill. It follows,therefore, that any reduction in the Weight or friction of the carriageis a matter of the highest importance, both in saving the strength andincreasing the efficiency of the operator.

The object of my present invention is to provide a shingle-machinecarriage of minimum Weight and maximum strength; a further object being`to provide bearings of such construction that the sliding friction shallbe reduced to minimum, a further object being to provideim provedmechanism for operating the movable dog, and improved iittings foruniting the several parts of the carriage, a further Object being toprovide simple means for adapting my new style of carriage to machinesiitted with the old style.

'Vith these ends in View my invention consists in certain features ofconstruction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure l is a top plan view ofthe carriageand ways. Fig. 2 is a view in side elevation, and Figs. 3, 4, 5, 6, 7,8, and 9 are detached enlarged views of parts.

A A represent a set of carriage-ways of the form hitherto in use, asrepresented in Letters Patent No. 272,316, granted to me February 13,1883.

B B represent the ways adapted to receive my improved carriage, and areshown in the accompanying drawings, ol" such form as will admit of theirbeing readily attached to the Ways A A. The way B is provided along itsinner edge with a horizontal bearing-surface, b. An upright surface, b',extends along the outer edge of the surface b, and a second horizontalsurface, b2, terminates the upright surface D. A met-al plate, C,L-shaped in cross section, has one edge bolted on the surface b2, whilethe opposite edge extends downwardly to a point a short distance abovethe inner edge of the way B, the plate C thus forming, with the way B, ahorizontal channel L-shaped in cross-section. The way B is provided onits inner face with a horizontal groove or channel, b3, about one-halfinchl in depth. Longitudinal ribs e3 a" are formed along the upper inneredges of the ways to guard the head-block and dog against injury inplacing the bolt.

The carriage-frame consists of two side rails, D D', a stationary dog,E, and a movable dog, E, constructed of steel tubing-in the presentinstance, about one inch in diameter. The use of steel tubing in thisconstruction is an important feature of my invention, as its greattenacity, combined with hardness, admits of its being made lighter thaniron tubing and yet being stiffer and more durable. The fittings whichconnect the stationary dog E with the ends of the side rails consist ofa tubular elbow, one branch of which, e, ts within the end of the dog E,and the other branch of which, (l, 4

fits over the end of the side rail, D. Figs. Sand 4 represent an endview aud top plan View, respectively, lof one of the fittings abovementioned. A perforation, e', is made through the branch e and dog E,which receives a rivetor bolt for securing the iitting rigidly to thedog. A perforatiomd, is made through the branch d and side rail,D,insuch a position that when the fitting is secured to the side rail by abolt, di, passing through said perforation, the fitting will lie ineloseproximity to the face of the Way B. A second perforation, di, of thesame diameter as the perforation d', is made through the rail D, aboutone inch from d ICO to admit of adjusting the dog E nearer the dog Ewhen sawing from shorter bolts. The branch d is provided witha slit, d,on its side which admits of its being closely clamped on the rail D bythe draw-bolt d. The sliding bearings F and F,which move in the channelsformed in the ways B' and B,respectively, are formed integral with orfirmly secured centrally to the ends ofshort tubesf, which latter areconstructed to tit snugly within the ends of the rails D and D', and arerigidly secured therein by rivets or other suitable means. The bearingsF consist of short bars which bear against the upper and lower sides ofthe channel b3, but have no lateral bearing within the channel. Thebearings F' are L-shaped in cross-section and fit within the L-shapedchannel formed by the way B and plate C secured thereon. They beardownwardly on the surface b, upwardly against the edge of the y plate C,and inwardly against the face b4r of the L-shaped plate C. Thelatterbearing is directly opposed to the drag caused by the saw-thrust.The outer portions of the bearings F are provided with recesses f',which render the bearings lighter, and are valuable as oil-receptacles.Figs. 5 and 6 represent side, end, and top plan views of the bearings Fand F, respectively. A set of steel holding-teeth G is secured to thestationary and the movable dog by means of blocks g, the

lblocks being hollowed out on the face in contact with the dog, toconform to the circular shape ofthe same, and having flat projections gat the point where they grip the tooth-bar g2. The blocks g are boltedor riveted to the dogs. The movable dog E is attached to the siderails,D D, by means of sleeves H, which iit and slide on the side rails,said sleeves being provided with short tubular projections h, formedintegral therewith or rigidly secured thereto, which projections fitwithin the ends of the dog E and are rigidly secured thereto. By thisconstruction the movable dog E serves the purposes of a girder andrenders a stationary end beam unnecessary. The sleeves II are furtherprovided with upright lugs K, rigidly secured thereto, which formbearings 7c for the tubular operating-rod L. The rod L is bent at rightangles at its front end and provided with an operating-handle, Z. Therod L is further provided just outside of the lugs K withdownwardly=projecting arms M, rigidly secured thereto. rIhe lower endsof the arms M are pivotally secured to links m, the links beingpivotally secured to the side rails at m.

From the above construction it will be observed that when the handle Zis pressed downwardly the sleeves and dog connected thereto will beforced inwardly toward the stationary dog. The motion is perfectlysimple and the construction such that the side rail is not extended inlength beyond absolute necessity, the weight of the carriage therebyreduced and its strength increased.

My improved carriage, constructed in the manner herein described,weighsless than my old-style carriage of the same carrying capacity,while the metal of which it is made is disposed in such form that amaximum strength is obtained and the resistance from friction reduced toa minimum.

It is evident that slight changes may be made in the form andarrangement of the several parts described without departing from thespirit and scope of my invention-for example, the introduction of atoothed sector in the place of arm M, the sector engaging a rack-barsecured to the side rails; hence I do not wish to limit myself strictlyto the construction herein set forth; but,

Having fully described my invention,what claim as new, and desire tosecure by Letters Patent. is-
